Processing the Coal. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Source: Energy Information Administration

Coking coal must also have low sulphur and phosphorous contents. Almost all metallurgical coal is used in coke ovens. The coking process consists of heating coking coal to around 1000-1100ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in a .

Coal utilization - Coal utilization - Carbonization (coke making): Coke is the solid carbonaceous residue that remains after certain types of coal are heated to a high temperature out of contact with air. The process of heating coal in this manner is referred to as carbonization or coke making.

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".
